F Street underpass work to close Interstate 15 lanes, ramp

LAS VEGAS — Construction will begin Sunday on the first phase of multiphase F Street connection project, which will reopen the F Street Underpass at Interstate 15.

Motorists can expect lane reductions and traffic shifts on northbound and southbound I-15 between U.S. 95 and Washington.

The initial work for the first phase will consist of lane shifts, the removal of median barrier rail and high mast lighting as well as temporary paving for future Phase 2 lane shifts.

Changeable message signs will be placed throughout the work zone, and the speed limit will be reduced to 55 mph in the work zone. Project work hours will run nightly from 7 p.m. to 6 a.m., Sunday night through Friday morning.

Starting at 7 p.m. Sunday, work will commence on the northbound I-15 lanes between U.S. 95 and Washington. Lanes will be shifted to the right (east), with three travel lanes, one exit lane to D Street and minimized shoulders (two feet). In addition, rolling lane closures will take place throughout the night. The D Street/Washington exit will close that night and reopen in the morning. The detour for the D Street ramp closure will be the Lake Mead Boulevard exit. The exit lanes to Washington and U.S. 95 will not be impacted during daytime hours.

On Monday and Tuesday, southbound I-15 lanes will be shifted to the right (west) and reduced from four travel lanes to three in order to restripe the southbound lanes. Rolling lane closures will also take place throughout the night. There will be lane closures on the median side of northbound and southbound I-15 on Tuesday, Wednesday and Thursday night to allow for the placement of temporary barrier rail to create a safe work zone.

The $13.6 million F Street project is collaboration between NDOT and the city of Las Vegas and is scheduled for completion in late 2014.
